Is Usual USD (USD0) Halal? Reserves, Interest and the Verdict

In January 2025, thousands of people who thought they were holding a dollar woke up to find their "dollar" trading at 89 cents. That was USD0++, the yield-bearing sibling of Usual's flagship stablecoin USD0, after the team announced a redemption floor of $0.87 without asking the holders who had been promised 1:1. If you are trying to figure out whether Usual USD belongs in a faith-conscious portfolio, that episode is the whole story in miniature: the base token is one thing, and the products built on top of it are something very different. So let me split them apart, because the answer to "is usual usd halal" depends entirely on which one you actually touch.

What USD0 actually is

USD0 is a stablecoin, and specifically what Usual calls a Liquid Deposit Token. It targets a hard 1:1 peg to the US dollar and is fully collateralized by tokenized Real-World Assets, overwhelmingly ultra-short US Treasury Bills and repos. That is the key structural fact. Usual does not park your money in a commercial bank the way USDC or USDT largely do. Instead it aggregates tokenized T-bill products from institutional issuers like Hashnote, M0, and Superstate into one permissionless token.

You get USD0 one of two ways. Direct mint: you deposit an eligible tokenized RWA and receive USD0 1:1. Indirect mint: you deposit USDC and a Collateral Provider supplies the matching T-bill collateral, and you get USD0 1:1. Either way, the thing sitting behind your token is short-dated government debt held in reserve, with on-chain visibility into the collateral.

Here is the part that matters for any faith screen. The reserve assets, Treasury Bills, are interest-bearing instruments. They pay a coupon. That yield is real, and it flows to the protocol. The question every framework below has to answer is: does the yield touch you when you simply hold USD0, or does it get intercepted before it reaches you?

For plain USD0, it gets intercepted. Base USD0 is non-rebasing and does not pay the holder interest. The T-bill yield accrues to the protocol and its governance/staking layer, not to your wallet balance. That single design choice is what makes the holding case defensible, and it is why you have to keep USD0 and USD0++ in separate boxes.

The three activities: holding, staking, and USD0++

Usual has a clean split, so use it.

Holding USD0. You hold a token pegged to a dollar, backed by T-bills, and you earn nothing. It is a payment and store-of-value instrument. No yield reaches you.

Staking into USD0++. You wrap USD0 into USD0++, a liquid staking token locked to a fixed four-year maturity. USD0++ pays a daily "coupon" denominated in the protocol's USUAL governance token. Usual explicitly markets this as "Alpha Yield," designed to outperform the risk-free T-bill yield. The reward is variable and depends on the secondary-market price of USUAL.

The revenue switch. When activated, protocol earnings (again, primarily the T-bill yield) get distributed weekly to stakers, sometimes in USD0 itself. This is the mechanism that pipes reserve interest to participants.

That taxonomy lines up almost exactly with how the Shariah Review Bureau frames staking questions: is the reward a share of genuine economic activity, or is it repackaged interest on a debt instrument? Hold that thought.

The Islamic verdict

Start with the easy parts. Is USD0 mal mutaqawwim, recognized property with lawful value? Under the permissive camp, yes. The Securities Commission Malaysia's Shariah Advisory Council ruled in 2020 that digital assets can be treated as mal and traded, and a dollar-pegged token backed by real reserves is far less speculative than a memecoin. The prohibitionist school associated with Mufti Taqi Usmani and Darul Uloom Karachi objects to crypto broadly on grounds of gharar, lack of intrinsic value, and absence of a sovereign backing, and a strict follower of that view would avoid USD0 on category grounds alone.

But even setting the blanket objection aside, USD0 has a specific problem the average stablecoin does not, and it is the same problem scholars like Sheikh Yusuf Talal DeLorenzo flagged years ago with T-bill-backed products. The reserve is riba-bearing by construction. Short-term US Treasuries are interest-bearing government debt. So the collateral itself is built from something a Muslim cannot own for the sake of its return.

Now the nuance, because this is where doctrine and inference part ways.

For plain USD0 held as a medium of exchange, the reasoned position (this is inference, not a settled ruling) is that it can be acceptable to the same degree scholars accept using regular fiat dollars. You are holding a claim on value at par, you receive no interest, and the fact that a custodian earns interest on reserves is analogous to a bank earning on deposits while you hold cash you do not profit from. Muslims use dollars daily without owning the Fed's bond portfolio. USD0 held for payments sits in roughly that lane. It is a tolerance based on need and the absence of personal riba intake, not an endorsement of the underlying instrument.

For USD0++ and staked yield, the picture flips. This is the clear riba case. The "coupon" is explicitly designed to pass through and amplify interest income from government bonds. Calling it Alpha Yield does not change the source. The four-year lock adds gharar, and the payout in a volatile governance token whose value drives the return adds a layer of maysir, speculation, on top. The January 2025 depeg, where the redemption terms were rewritten and USD0++ fell toward 87 cents, is a live demonstration of that gharar: holders thought they had a firm 1:1 claim and discovered the rules could move. No mainstream framework, permissive or prohibitionist, gets you to a comfortable "yes" on USD0++. The prohibitionists reject the whole category; the permissive scholars who allow crypto still reject interest, and this is interest wearing a token costume.

So the Islamic split is: base USD0 for transactions, defensible under a need-based tolerance; USD0++ and the revenue-switch yield, not permissible.

Christian, Jewish, and LDS lenses

The interest question does not disappear when you change traditions; it just gets weighted differently.

Catholic (USCCB). The US bishops' Socially Responsible Investment Guidelines are built around excluding specific harms: weapons, abortifacients, pornography, and grave human-rights abuses. A T-bill-backed stablecoin trips none of those product screens. Catholic moral theology no longer treats ordinary interest as usury the way the medieval church did, so USD0 clears the USCCB exclusions cleanly. USD0++ raises a prudence question about speculation, not a doctrinal exclusion.

Christian BRI (Biblically Responsible Investing). BRI's six categories track abortion, pornography, and similar issues rather than interest, so USD0 passes on product grounds. The BRI-flavored caution here is stewardship: is locking dollars into a four-year, token-denominated yield instrument that already broke its peg once a wise use of what you have been entrusted with? That is a wisdom call, not a prohibition.

Jewish (Halakhic). This is where it gets interesting, because Judaism has a live prohibition on interest between Jews (ribbis). The Bais HaVaad and similar authorities apply a two-tier analysis: interest between Jews is forbidden and typically requires a heter iska (a partnership restructuring) to permit business financing, while interest from a non-Jewish or government issuer is treated far more leniently. USD0's reserve yield comes from the US Treasury, a government, so the reserve interest itself is not the classic ribbis problem. Holding USD0 is fine. USD0++ is where a careful posek would want a heter iska framing or would flag the arrangement, since you are now personally taking a structured return that looks like lending at interest.

LDS (Word of Wisdom and the Oaks speculation warning). The Word of Wisdom is about the body and does not speak to stablecoins. The relevant text is Dallin H. Oaks' 1971 warning against speculation, gambling with money you cannot afford to lose in search of quick gain. Holding USD0 as a dollar substitute is not speculation. Staking into a four-year-locked, governance-token-paid Alpha Yield that has already depegged is close to a textbook example of what Oaks cautioned against. So the LDS read mirrors the others: the base coin is boring in the good way, the yield product is not.

The FaithScreener verdict

Put it together and the verdict is genuinely split by activity, not by coin.

Base USD0, held as a dollar-equivalent for payments and stablecoin liquidity, lands as conditionally acceptable across all four frameworks: no personal interest intake, real reserves, low speculation. The condition is that you treat it as cash, not as an income asset, and that a strict prohibitionist Muslim may still avoid it on category grounds.

USD0++, the staking module, and the revenue switch land as not compliant on the Islamic screen (pass-through riba plus gharar plus maysir) and as caution/avoid on the Christian, Jewish, and LDS speculation-and-lending grounds. Same token family, opposite answer, because the yield changes what you are actually doing.

You can check where USD0 sits right now, with its live reserve and layer analysis, in the USD0 crypto report. If you want to compare it against other T-bill-backed and algorithmic stablecoins, the full crypto screening dashboard shows the layer flags side by side, and the screening frameworks page explains exactly how each faith's thresholds get applied.

The Bottom Line

USD0 the stablecoin and USD0++ the yield token are two different questions with two different answers. If you hold USD0 as a dollar substitute and earn nothing, it is defensible for most Muslims (as a need-based tolerance, not an endorsement of its T-bill reserves) and clears the Catholic, BRI, Jewish, and LDS screens. The moment you stake into USD0++ to collect the Alpha Yield, you are taking pass-through interest wrapped in a volatile governance token with a four-year lock, and that fails the Islamic screen outright and draws a speculation caution from the other three. The one thing to remember: with Usual, the compliance line is not the coin, it is whether the yield reaches your wallet.
